LAWN-SPRINKLER.

SPECIFICATIONfofming part of Letters Patent No. 347,359 dated August 1'7, 1886.

Applicaiionfiled April 23, 1885. Serial N0. 163,J04. (No model.)

- To all whom it may concern:

which-- Figure 1 is a perspective view of my improved sprinkling device with hose-stem attachment; Fig. 2, an enlarged sectional view .of the spraying attachment, and Figs. 3 and 4 modified forms of the hose attachment.

The present improvement relates to an improvement in the class of articles known as lawn-sprinklers and spraying devices, in which Iprovide a cup-shaped device fitted on one end of the metal part attached to a hose, the-upper part of the said cup being provided with a series of openings, and centrally having a stem upon which a revolving head is placed, having thereon a series of'spiral blades or wings slightly cup-shaped, so that the water in passing through the openings in the head and striking these spiral blades will spray the water, and at the same time cause the said head to revolve, and thus distribute the water evenly, all of which will now be set forth in detail.

In the accompanying drawings, A represents a cross-joint provided at its lower end v with a portion, 13, sharpened at the end and designed to be pushed into the ground. One of the openings, 0, is designed to have a-hoseconnection, D, therewith leading to any suit able reservoir, the opposite opening to have a short piece, D for the foot to press on, and to the upper part is connected therewith a short section of gas-pipe, E. At the upper end of this gas-pipe, which is threaded externally, I provide'a cup-shaped part, F, having therein a female screw to correspond with the threaded gas-pipe. The head-of this cup is provided with aseries of vertical openings, G, therein, preferably near the periphery of the said head. Centrally this head has a vertical stem, H, formed integral therewith, the upper end provided with a nut, I. Upon this stem H, I provide a revolving piece or head,

J, secured'thereon by nuans of nut I. The upper peripheral part isflanged outwardly somewhat, terminating in a series of spiral blades, J, preferably eight in number, each alternate blade, K, somewhat larger than the intermediate blades, L. The base ofthelarger blade K, commencing at the lower part of the head J, makes a partial convolution about the head J, extending somewhat outwardly at an angle, so that when the Water is forced through the openings G it strikes the under surface of the said spiral blades, and being deflected, thus forms a spray, and at the same time the forced water will cause the head to revolve, and thus assist in spraying and distributing the water evenly.

Sometimes I find it convenient to dispense entirely with the cross-shaped pipe-connec tion, and attach the hose directly to an L- .shaped device, with an additional part east thereon, forming one piece, M, the lower end being horizontally disposed, and a female screw-threaded nut in it to connect directly on the hose, also, a short projecting part, 0. in which I put a short piece, intended to push in the ground to hold the whole in an upright position, as shown in the drawings.

' In Fig. 4 is shown a modification of Fig. 3,

in which the cup F, as shown, is attached to this support of the L-shaped piece.

I am aware that it is not broadly new to apply to the end of ahosc used in lawn'sprinkling a rotary spiral sprinkler; but

\Vhat I claim is In a lawnsprinkler, a spraying device consisting of the cup-shaped part F, having vertical openings Gr near the periphery of its head, and a vertical stem, H, in combination with the rotary head J, having external large spiral blades, K, and the smaller blades L, and the nut I, all constructed, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of I April, 1885, in the presence of witnesses.
